CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 644,632, dated March 6, 1900'. Application filed August 5, 1899. Serial No.726, 2 28. (N model.)

T0 on whom it may concern.-

Be it known that I, CHARLES O. PEER, of Springfield, Greene county, Missouri, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification.

My invention relates to car-roofs, and more especially to that type embodying an inner or 'metallic section which accommodates itself to expansion and contraction of the roof and an outer or wood section suitably braced apart in order to provide an air-space through which the outside air may freely circulate, and thus prevent the temperature of the car from rising as high as it would if a one-section roof were employed, my object in this connection being to provide a car-roof of the character above outlined which is an unfailing guard against the entrance of water to the car and is constructed in sections, so that a defective part may be replaced without tearing up the entire roof, my further object being to provide a roof which is comparatively inexpensive and of simple, strong, and durable construction. 1

To the above purposes the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed,and in order that the invention may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1 represents a sectional perspective view of a car-roof embodying my invention. Fig. 2 is an enlarged section taken on the line II II of Fig. 1. Fig. 3 is a section on the same scale as Fig. 2 and taken on the irregular line III III of Fig. 4:. Fig. 4: is a longitudinal section taken on the irregular line IV IV ofFig. 3. Fig. 5 is a cross-section taken on the line III V of Fig. 4, but showing-the filling-block in elevation; Fig. 6 is a detail perspective view of said filling-block. Fig. 7 is an enlarged cross-section taken on the line VII VII of Fig. 2. Fig. 8 is an elevation, broken away, of the upper end of one of the supercarlines. Fig. 9 is a detail perspective View of one of the supercarline filling-blocks. Fig.

10 is a perspective, as viewed from below, of

the juncture-point of a pair of the ridge caps or crestings and the supercarline.

Referringto the drawings, where like reference numerals designate corresponding parts, 1 designates a side, 2 one of the longitudinal upper sills, and 3 a carline of an ordinary box-car, the carlines being connected at their apex by the longitudinal ridge-bar 4 and between the same and thesills by the lower purlins 5, as usual. w

6 designates one of the fascia-moldings, 7 one of the crown-moldings, arranged to project some distance above the fascia-molding,

and 8 a series of separating-blocks arranged at intervals between said moldings and bolted with the latter to the sill 2, as shown at 9, or in any other suitable manner.

10 designates a series of filling-strips which are secured upon the ridge-bar in longitudinal alinement and with their ends abutting against the ridge-filling blocks, (designated generally by the letters R B,) said fillingblocks consisting of the elongated and longi tudinally-extending body portion 11, formed centrally with the u pwardly-proj ectin g transverse rib 12, through the center of which extends the vertical bolt-hole 13. The body portion 11 is provided with the laterally-projecting wings 14 of substantially inverted-T shape when viewed from the side, with the stems 15 of said Ts projecting upward almost as high as and arranged in alinem ent with the lug 12 of the body portion and with the branches or arms of said T hollowed or grooved so as to form the segmental cavities 16 at opposite sides of the body portion 11.

S O designate generally my improved supercarline, the same being constructed, by preference, of sheet metal and bent to form the longitudinal channel or groove portion 17, the laterally-projecting arms 18, and the gutters 19, the same being arranged vertically below arms 18 and having their extreme inner ends upset or bent upward, as shown at 20, in order that water discharged into said gutters shall not escape from their inner ends in case such ends assume as low a level as their outer ends under the twisting or turning of the car, particularly when turning sharp curves where the track-bed is banked. These supercarlines rest at intermediate points upon the lower purlins 5, and are secured to the same and to the sill 2 by lagscrews 21 or bolts, it being preferred that lagscrews be employed for engagement with the sill 2, owing to the great thickness of the latter, and bolts with the purlins, though one is obviously the mechanical equivalent of the other. In each case it is desirable to use a filling-block 22, the same being fitted up into the channeled or grooved portion of the said carline and resting upon the purlin or sill below, the securing screw or bolt extending also through said block, as shown most clearlyin Fig. 7. To add still further to the rigidity and strength of the structure and as a support for the outer section of the roof hereinafter referred to, the upper purlins 23 (one only of which appears) are employed, said upper purlins extending longitudinally of the car and resting upon the supercarlines, being bolted to the latter in an obvious manner, and in this connection it may be stated that it is desirable to employ filling-blocks 22 in the supercarlines to receive the bolts uniting the latter to the upper purlins in order to act as washers and also to stilfen and strengthen the supercarlines at the points where they receive the pressure of the roof hereinafter referred to.

The outer ends of the supercarlines rest upon and project slightly beyond the faciamolding C, while their upper ends envelop and rest upon the wings of the filling-blocks, the channeled portions fitting down over the stems 15, the flanges 1'8 overhanging the hollowed parts of said wings and the gutters fitting down snugly into said hollowed or grooved portions 16 of the wings, (see Fig. 4,) the upper ends of the supercarlines bearing against the body portion of the block to limit movement toward each other, though they are free to move in a limited degree outward and thereby accommodate the lateral expansion and contraction of the car.

The ridge cap or cresting 2i is formed in sections, which extend between the supercarlines and are interlocked with the said carlines and with each other. The said caps or crestings as viewed in cross-section are slightly-bowed downward and rest upon the ridge-filling blocks 10, and being wider than the latter project beyond the same some distance and completely envelop the fillingblocks R B and the upper ends of the supercarlines. They are constructed by preference of sheet metal and to impart the required rigidity and strength are of double construction outward of the ridge filling strips. At the points coinciding with the sides of stems 15 of the filling-blocks the inwardly-turned flanges 25 effecting this double-strength construction are bent downward and outward, being crimped near their outer ends to form the approximately V-shaped gutters 26, which gutters, it will be understood, extend from the stems 15 of one filling-block to the stems 15 of the other, and therefore terminate over the hollowed or grooved portions 16 of the filling-block. Beyond the ends of said gutters said caps or crestings are bent to inverted-U shape, as shown at 27, the U- shaped portion of one strip fitting snugly in the U-shaped portion of the adjacent strip and over the filling-block and the interposed upper ends of the supercarlines engaging the wings of said filling-block, as described, the ends of the flanges forming the gutters 26 of said caps or crestings projectinginto the upper ends of the gutters 19 of the supercarlines, as shown clearly in Figs. 3, 4, and 10, in order that any water blown up under the overlapping caps or crestings into the gutters 26 may be discharged from the ends of the latter into the upper ends of the supercarline-gutters and, flowing down the latter, will be discharged to the ground through the space between the fascia and crown moldings of the car, as will be readily understood, the upset or closed upper ends of the supercarline-gutters preventing the escape of water from the upper end of the same should the car tilt sufficiently in rounding a curve to raise the outer ends of the supercarlines level with their inner ends.

The inner section of the roof is completed by the roof-plates 28, preferably of corrugated iron, the same being fitted at their edges be tween the flanges 18 and gutters 19 of the supercarlines and slid inward until their inner ends overhang the flanges forming the gutters of the caps or crestings, as shown most clearly in Fig. 3, the outer ends of said roofplates bearing against and,by preference, projecting into the grooved faces of the separating-blocks 8, which thus maintain the upper ends of the roof-plates in position to discharge any water which is blown upward upon the same into the gutters 26 of the caps or crestings, to be discharged thence into the supercarline-gutters, as hereinbefore made clear.

29 designates a supplemental ridge-bar ex tending from one end of the car to the other upon the arched or U-shaped portions of the caps or crestings and secured to the same by means of the vertical bolts 30, which extend through said ridge-bar, the overlapped ends of adjacent caps or crestings, the fillingblocks, and the ridge-bar 4, and are engaged at their lower ends by clamping-nuts 31. (See Figs. 3 and 5.) This ridge-strip, as usual, forms the support for the upper end of the wood or equivalentroof-boards 32, forming the outer section of the roof, and resting and secured in the usual manner at their outer ends upon the crown-moldings 7 and at intermediate points upon the upper purlins 23. This wood root obviously protects and preserves the metallic roof and at the same time provides an air-spacethrough which the air may circulate from end to end and side to side of the root, as partially indicated by the arrows, Fig. 2, the air in its lateral passage passing between the upper purlins and the roof-plates and between the ridge-bar 29 and the depressed or body portions of the caps or crestings 24, as indicated in Fig. 1. Under any longitudinal expansion or contraction it is obvious that the roof-plates are free to play laterally in the space between the supercarline-flange 18 and gutters 19. (See Fig. 4 particularly.)

From the above description it will be apparent that I have produced a car-roof which embodies the features of advantage enumerated as desirable in the statement of invention, and it is to be understood that while I have shown the preferred embodiment of my invention I reserve the right to make all changes which properly fall within its spirit and scope.
